1. INTRODUCTION
Application
The VF05 two-wire guided microwave level transmitter is used to measure the distance, level, and volume of liquids, solids, and granules. The device can be used in
storage and reaction tanks, rigid pipelines of suitable diameter, and level reference vessels. The device is HART capable, it can be programmed using HyView software
or PACTWARE.
Operating Principle
The VF05 two-wire guided-microwave level transmitter measurement method is based on TDR (Time Domain Reflectometry) analysis of the electromagnetic pulse
traveling along the probe. The device sends nanosecond-wide, low-power pulses along an electrically conductive rod, cable, or coaxial supply line at a known rate of
light propagation speed. If the electromagnetic pulse propagating along the conductor reaches a medium boundary with a different (r) dielectric constant (the surface
of the measured medium or the phase boundary of two liquids), some of the energy is reflected from there. The larger and sharper the (r) dielectric constant change
at the boundary of the media, the better the efficiency of the reflection (e.g., 80% of the energy is reflected from a flat air-water boundary) is.
The pulse is detected and processed by the device as a voltage signal. Since the propagation speed is known, the distance of the reflecting surface can be determined
by measuring the travel time of the pulse. The travel time is the time between the start of the pulse and the arrival of the reflected pulse, and the distance traveled is
twice the distance to and from the target. The device calculates the distance from the measured time into an electric signal proportional to the distance, an output
current of 4…20 mA, and provides a HARToutput signal and displays it on the display. Other derived quantities (volume, weight, etc.) can also be obtained from the
distance data using the device software. The advantage of the described measurement technology compared to other level measurement methods is that the dust,
foam, steam, boiling, and surface turbulence have no disturbing effect.

3.2. ACCESSORIES
•Hyview software •2× M20x1.5 cable gland
•User and Programming manual •VGF-DISPLAY display unit (option)
3.3. CONDITIONS FOR SAFE USE
▪The metal housing of the device must be connected to the equipotential (EP) network.
▪The aluminum content of the cast aluminum housing exceeds the limit value, so the equipment must be protected against impact and friction.
3.4. MAINTENANCE AND REPAIR
VF05 does not require maintenance on a regular basis. In some very rare instances, however, the probe may need cleaning to remove deposited material.
This must be carried out gently, without damaging the probe. Repairs during or after the warranty period are carried out exclusively at the Manufacturer. The
equipment sent back for repair should be cleaned or disinfected by the User.

4. INSTALLING
4.1. HANDLING AND STORAGE
Lift the instrument using both hands, or if necessary, use a hoist. Do not lift the instrument
by the probe. It is a critically sensitive part.
Protect the instrument from mechanical impacts and falling. The electronics
is a sensitive and fragile unit.
Do not bend coaxial and rod probes.
The device must be supported in the marked places.
The cable probe must not be looped, broken, or frayed.
The minimum bending diameter is 0.4 m (16″).
All these may cause a measurement error.
Storage temperature:
4.2. MOUNTING ON CONTAINERS
4.2.1. General mounting instructions
The size and position of the connector on the top of the tank (and the distance from the wall), the internal anti-reflection fittings, the rough joints, the welds and the
shape and design of the top and bottom of the tank are very important for the correct operation of the device. Any factor that affects the formation of the electromagnetic
field of the probe also significantly impairs the measurement accuracy. The coaxial probe is an exception because it has no external electromagnetic field.
Threaded process connection
Lifter height
Lifter intrusion into the tank
The easiest way to mount onto the tank is with a
device screwed into a 1 "BSP, 1" NPT, 1½ "BSP
or 1½" NPT threaded hole.
Do not use a lifter longer than the probe diameter
for individual probes and dusty applications.
h ≤ Ød, where
h = lifter height
Ød = lifter diameter
Consult HYCONTROL if the above condition cannot
be met!
The lifter must not extend into the tank,
as the protruding part interferes with the
measurement!

9 / 27
Mounting two devices
Effects of material influx
Using a protective tube
If two devices have to be mounted on one
tank, they must be spaced at least 2 m
(6.5 ft) apart to eliminate interference and
measurement inaccuracies resulting from
the interaction of the two electromagnetic
fields.
Devices equipped with coaxial probes are
not subject to the above warning because
there is no electromagnetic field outside the
probe's outer sheath.
Do not place the lifter near the material inlet
pipe connector.
Material flowing onto the sensor probe causes
incorrect level indication. If there is not enough
space, it is recommended to install a baffle plate.
The floating lid is a common solution for petrochemicals. In
such cases, the use of a damping tube is recommended.
Straightness and contact of measuring probes
with other fittings and distance from the bottom of the tank.
Using a stirrer
After installation, the cable probes and the associated tensile weight
must be straight, tensioned, and away from other fittings (e.g.,
mixer). They must not come into contact with the tank wall, bottom,
or other objects.
The installation space requirements of the different measuring
probes must be taken into account according to the data of the
measuring probes (see Technical Data).
There is no radiation cone along the probe.
When measuring liquids, the use of a reference chamber or damping tube is
recommended, since it provides mechanical and electromagnetic protection for accurate
measurement.
Protect the device from direct sunlight!
Attaching the probe to the bottom of the tank.
Flexible cable probes can be anchored to the bottom of the tank with a fastener or loop.
Installing and shortening the cable probes
If necessary, the probe can be shortened, but only for liquid applications.
Steps:
1. Loosen the grub screws (hexagon) with an Allen key. (ISO 2936)!
2. Pull the cable out of the tension weight and cut to the desired size!
3. Insert the cable back into the weight as shown and tighten the screws!
4. Modify the configuration parameters to the new length, the reference point being the
upper edge of the weight!

4.2.2. Installing the Device for Measuring Solids
False measured value
Coning and strong tensile force on the probe
The probe may not touch the lifter pipe
Strong tensile force. The rope must not be
anchored when measuring solids.
The device is mounted at a distance of half the
radius of the tank from the top of the tank with a
minimum lift nozzle height.
It prevents excessive mechanical stress when
emptying the tank.
The tensile force of the probe rope depends on the height and shape of the
tank, the fragmentation of the material, the density, and the speed of
discharge.
The following table gives the tensile load values for the different materials
(approximate data in tons).

The measured process material can accumulate on the probe and lifter, which weakens the energy of the measuring pulse.
Avoid creating cavities that increase deposition.
Observe the load capacity of the tank top, which must ensure the maximum tensile force of the probe.
